Definitions
- the present invention relates to a machine tool for machining a workpiece. Furthermore, the present invention relates to a method for machining the workpiece on the machine tool.
- Traveling column machines are state of the art nowadays when it comes to machining large-volume and / or very heavy workpieces.
- the machines can have a tool changing device, which is located behind a cover that can be opened and has tools ready for machining the workpiece. If the tool is now to be changed, the cover opens and the tool changing device can be moved to the work spindle in order to carry out the tool change there.
- the known machine tools are often designed in such a way that such a tool change has to take place at a defined position within the tool and gm asc, namely usually in the vicinity of one at the Machine tool fixed tool magazine.
- the working lockers! must be moved to the specified position for each tool change process, which leads to an increase in the machining time of the respective workpiece.
- An object of the present invention is therefore to provide a machine tool for machining a workpiece, with which the above-mentioned problems are avoided.
- the machine tool according to the invention for machining a workpiece has: a machine table for clamping the workpiece, a work spindle for receiving a tool for machining the workpiece, a work space which is essentially delimited by the machine table and at least a first cover, and a tool changer which is arranged outside the work area and is set up to change the tool accommodated in the work spindle, the machine tool also being set up to move the first cover when changing the tool, thereby expanding the work area of the machine tool by a tool change area and opening up an access area , through which the tool changer can be moved into the tool change area, and the work spindle is positioned in the tool change area in such a way that the tool changer inside the tool received by the work spindle half of the tool changing area.
- the machine tool according to the invention is set up in such a way that the expansion of the work space by the tool change area and the release of the access or access area for the tool changer, through which the tool changer can be moved into the tool change area, takes place at the same time, since for both processes only the a movement of the first cover is necessary.
- the two steps can therefore take place in parallel, which leads to a reduction in the tool change time and the chip-to-chip time.
- the machine tool according to the invention makes it possible to remove material chips and cooling lubricants that settle on the carrier during machining by providing wipers, so that the material chips do not deposit on the carrier nor that the material chips go to the feed mechanisms of the work spindle (along the x, y and z axes). This additionally increases the reliability of the machine tool.
- the structure of the machine tool could be made even more compact by the tool magazine carried alongside the carrier, so that the tool change time could be reduced considerably.
- the machine tool according to the invention has a higher stiffness with the same or a lower casting mass, which additionally has a positive effect on the thermal stability and a higher geometric accuracy. This also had a positive impact on machine dynamics.
- An advantageous further development of the machine tool consists in that the working space of the machine tool is essentially limited by the machine table, the first cover and a second cover.
- the working space available for machining the workpiece could be enlarged by the principle with the movable first cover and the second cover and partition between the working space and the traveling column of the machine tool.
- the released access area runs essentially perpendicular to the second cover.
- the machine tool according to the invention can advantageously be further developed in that the released access surface runs essentially perpendicular to the machine table.
- the machine tool according to the invention in a particularly advantageous manner in that the access area is separated from the working space of the machine tool by the first cover and the second cover during machining of the workpiece, the first cover and the second cover are arranged substantially coplanar to one another during the machining of the workpiece and separate the tool changing area from the working space.
- a separation of the tool change area and the infeed mechanism of the tool spindle from the work area during machining of the workpiece has a positive effect on the reliability of the machine tool, since no material chips or cooling lubricants get into the tool change area or in the infeed mechanisms and can possibly contaminate and / or damage them.
- a particularly advantageous development of the machine tool according to the invention consists in that at least the first cover is moved in one direction out of the work area in order to expand the work area of the machine tool by the tool changing area.
- the machine tool according to the invention can advantageously be further developed in that at least the first cover is moved by a separate drive independently of the drive for moving the work spindle.
- the first covering can be moved independently of the travel movement of the work spindle, since only in this way, for example, the wipers can reliably remove the material chips accumulated on the carrier and the cooling lubricant / cooling lubricant.
- the machine tool according to the invention can advantageously be further developed in that the work spindle is arranged on an end section of a movable carrier which travels in the longitudinal direction through an opening in the first cover.
- the opening in the first cover enables the carrier and thus the work spindle to be moved independently of the first cover.
- the machine tool can be further developed in that the clamping surface of the machine table spans an x-y plane and the first cover essentially spans an x-z plane.
- An advantageous development of the machine tool according to the invention is that the work spindle is positioned in the tool change area by moving the carrier along its longitudinal direction in order to position the work spindle in the direction of the y-axis.
- the machine tool according to the invention can be developed in a particularly advantageous manner in that the tool changer is arranged on a tool magazine which is arranged laterally spaced apart from the carrier in the x direction.
- the machine tool according to the invention can be developed particularly advantageously in that the tool magazine is separated from the working space of the machine tool by the first cover and the second cover during the machining of the workpiece, the first cover and the second cover being substantially coplanar during the machining of the workpiece are arranged to each other.
- a separation of the tool magazine from the work area while machining the workpiece has a positive effect on the reliability of the
- Machine tool since no material chips or cooling lubricants get into the tool magazine, in the linear axis or in the tool changer and can possibly contaminate and / or damage them.
- An advantageous further development of the machine tool according to the invention consists in that the tool magazine and the tool changer are moved parallel to the carrier during the movement of the carrier in the x direction.
- the tool magazine can be carried in the x direction with the movement of the carrier (and the work spindle).
- a tool change can be carried out at any position on the work spindle along the x-axis, which avoids additional infeed movements of the work spindle and can in turn reduce the tool change time and the machining time of the workpiece.
- the machine tool according to the invention can advantageously be further developed in that the tool magazine has a linear axis which moves the tool changer through the access area into the tool changing area by which the working space of the machine tool has been expanded.
- the linear axis can advantageously be provided so that the tool changer can get from its position separated from the work area behind the first and the second cover into the tool changing area in order to carry out the tool change there on the work spindle.
- the machine tool according to the invention can advantageously be further developed in that the tool changer is designed as a double gripper.
- any other configuration of a tool changer can also be provided in the machine tool according to the invention.
- the machine tool according to the invention can advantageously be further developed in that the opening in the first cover, through which the carrier extends, has at least one scraper which, when the working spindle is moved in the direction of the first cover, contains material chips and / or cooling lubricants stripped from the carrier.
- the at least one scraper advantageously enables the carrier to be cleaned / cleaned of adhering material chips and cooling lubricants.
- the machine tool also has a drain plate below the first cover, which collects cooling lubricants and material chips flowing off the first cover during tool change and leads them off to a collecting area.
- the stripper After the stripper has stripped off the material chips and the cooling lubricant from the carrier, this flows down on the first cover and should advantageously be deliberately fed to a preparation. This enables the drain plate, since it contains the dripping cooling lubricants and the material chips e.g. feeds a collection area below the machine table, from where the cooling lubricant can be passed on and prepared inside or outside the machine tool.
- the method according to the invention for machining the workpiece on the machine tool in accordance with an NC program comprising a machine table for clamping the workpiece, a work spindle for receiving a tool for machining the workpiece, a work space which essentially extends through the machine table and at least one first Cover is limited, and a tool changer, which is arranged outside the work area and is set up to change the tool accommodated in the work spindle, has the following steps: clamping the workpiece on the machine table of the machine tool, picking up the tool for machining the Workpiece in the work spindle, machining of the workpiece according to the NC program, the following steps are carried out during a tool change: moving the first cover, whereby the work space of the machine tool is expanded by a tool change and an access area is opened through which the tool changer can be moved into the tool change area, Moving the tool changer through the released access area into the tool change area, and positioning the work spindle in the tool change area in such a way that the tool changer can change the tool picked up by
- the method according to the invention now enables faster processing of a workpiece, in particular if different tools have to be used for this and therefore a tool change must be carried out regularly.
- the method has the advantages of the machine tool according to the invention described, in particular the advantages that the tool change can take place outside the working area of the machine tool and the risk of collision of the tool changer with the workpiece or clamping device of the workpiece has thereby been significantly reduced.
- the method according to the invention can advantageously be developed further in that the method of the tool changer takes place through the released access area into the tool changing area independently of the step of positioning the work spindle in the tool changing area.
- the method according to the invention can advantageously be further developed by moving the work spindle in the direction of the first cover independently of the method of the first cover to expand the work space by the tool changing area.
- the machine tool according to the invention significantly reduced the risk of the tool changer colliding with other elements in the work area, since the tool change takes place outside the work area. Furthermore, the machine tool according to the invention has made it possible to achieve a more compact construction of the machine tool, which has led to an increase in machine dynamics and rigidity and thus to an increase in precision during machining. This also improved the thermal stability of the machine structure.

- FIG. 10 shows a flow chart of an exemplary embodiment of the method according to the invention for machining the workpiece
- FIG. 1 schematically shows the machine tool i ne 100 according to the invention in a closed state in which no tool change can take place.
- the machine tool 100 has, in addition to the work spindle 20 arranged on the carrier 22 and the machine table 10, the first cover 30 and the second cover 40.
- the state of the machine tool 100 can be seen in FIG. 1, in which the first cover 30 is arranged essentially coplanar with respect to the second cover 40. This is always the case, for example, when a workpiece that is clamped on the machine table 10 is to be machined by the work spindle 20 using a tool.
- a wide variety of tools can be accommodated in the work spindle 20, in particular tools for machining the workpiece, which for example have a standardized receptacle such as a hollow shank taper or a steep taper.
- tools for machining the workpiece which for example have a standardized receptacle such as a hollow shank taper or a steep taper.
- other tool holders specific to the manufacturers of the tools can also be received by the working spindle 20.
- a suitably equipped work spindle 20 is of course a prerequisite for this.
- clamping devices such as clamping claws, mechanical or hydraulic workpiece clamps, a wide variety of jaw chucks etc. can in turn be used to clamp the workpiece on the machine table 10.
- FIG. 2 schematically shows a detailed view of the machine tool 100 according to the invention in the state of the tool change with the tool changer 50 moved into the tool change area 80. 2 shows in detail that the first cover 30 is set back in relation to the second cover 40. This resetting is carried out by a drive 35 (not shown here, see FIG. 5 for this) on the first cover 30 when a tool change is imminent.
- the first cover 30 is reset by the drive 35 with respect to the second cover 40, around the working space 70 delimited by the first cover 30 and / or second cover 40 and the machine table 10 (not shown here, see here FIG. 5) Tool machine 100 to be expanded by a tool changing area 80 (not shown here, see FIG. 5 for this).
- elements e.g. machine table, mounted clamping device for the workpiece etc.
- FIG. 2 shows a particularly advantageous embodiment of the machine tool 100 according to the invention, in which, by resetting the first cover 30 relative to the second cover 40, an access area 42 is simultaneously released, through which the tool changer 50 (here designed as a double gripper) into the tool changing area 80 can be moved.
- the tool changer 50 here designed as a double gripper
- the access surface 42 extends essentially perpendicular to the first cover 30 (and thus also essentially perpendicular to the second cover 40). If the first cover 30 is moved in a direction that extends out of the working space, a surface is created between the first cover 30 and the second cover 40 that is arranged essentially perpendicular to the first cover 30 and the second cover 40.
- the tool changing area 80 can be generated with only one movement of the first cover 30 and at the same time access in the area (access area 42) can be enabled for the tool changer 50 .
- such a configuration of the first cover 30 and the second cover 40 has the advantage of keeping the structure of the machine tool 100 compact in the area of the devices required for the tool change.
- the tool changer 50 and also a tool magazine 60 (not shown here, see here FIG. 8) through the first cover 30 and / or through the second cover 40 from the working space 70 Cut.
- cooling lubricants supplied during the machining of workpieces as well as material chips removed from the workpiece are distributed in the work space 70, so that these of course also contaminate the tool changer 50 and / or the tool magazine 60 and, as a result, may even damage them. Protection of these devices from the cooling lubricants and from the material chips is therefore appropriate and increases the reliability of the machine tool 100 according to the invention.
- FIG. 3 schematically shows the machine tool 100 according to the invention in the closed state with an x-y plane spanned by the machine table 10.
- the machine tool 100 according to the invention is reduced to the elements of the first cover 30 and the second cover 40 as well as the machine table 10 and the work spindle 20 in order to keep the machine tool closed 100 if the first cover 30 and the second cover 40 are arranged substantially coplanar with one another.
- the second cover 40 can consist of a plurality of individual segments that can be moved into one another, so that the first cover 30 not only moves in the y direction (corresponds to a direction that extends out of the working space 70), but also along the x axis can be. Furthermore, the second cover 40 can also be constructed from segments which can be folded together / pushed together like a bellows.
- the first cover 30 can be built from several different sections on ge. For example, below and / or above the carrier 22 of the work spindle 20, similar to the second cover 40, a plurality of individual segments which can be moved into one another can be provided in the first cover 30, which enable the carrier 22 and thus the work spindle 20 in FIG to move in the z direction and thus enable the work spindle to be fed along the three axes (x, y and z axis).
- FIG. 4 schematically shows the machine tool 100 according to the invention in the state of the tool change with the x-y plane spanned by the machine table 10.
- the access surface 42 for the tool changer 50 is arranged in the exemplary embodiment described in FIG. 2.
- the tool cover area 80 is generated by a single movement of the first cover 30 in one direction out of the work area or away from the work area and at the same time the access area 42 is released, so that the tool changer 50 ( executed here as a double gripper) can be moved into the tool changing area 80.
- a tool change outside of the work space 70 is thus advantageously possible.
- FIG. 4 shows the drain plate 90 below the first cover 30, which collects cooling lubricant dripping from the first cover 30 and / or material chips removed from the workpiece during the tool change, and it a collection area, which can be located below the machine table 10, for example. From this collection area, material chips and cooling lubricant can be supplied for processing inside or outside the machine tool 100.
- the tool changer 50 can be of any type and is not limited to the embodiment of a double gripper.
- FIG. 5 schematically shows a sectional view of the machine tool 100 according to the invention with the division of the working space 70 and the tool changing area 80.
- FIG. 5 shows the position of the tool change area 80 (shown here by dotted lines) by which the work space 70 (shown here by dashed lines) is extended by the method of the first cover 30 in relation to the work space 70.
- the working space 70 is essentially delimited and defined by the machine table 10 (or its clamping surface 12) and by the first cover 30 and / or the second cover 40 when the first cover 30 is arranged essentially coplanar with the second cover 40.
- the first cover 30 is now moved such that the tool change area 80 was created in the immediate vicinity or directly adjacent to the working space 70.
- the tool changer 50 can now be moved into the tool changing area 80 through the access surface 42, which was released by the movement of the first cover 30. If the work spindle 20 is now also positioned in the tool change area 80, the tool picked up by the work spindle 20 can be replaced by the tool changer 50.
- the carrier 22 and thus the work spindle 20 can be moved in the y direction by a corresponding drive 25, regardless of the movement of the first cover 30, which is accomplished by a separate drive 35 .
- the drain plate 90 collects cooling lubricant and material chips, which can drip / fall off from the first cover 30 during the tool change, and feeds them to a collection area (e.g. below the machine table 10), so that the material chips and the like used cooling lubricants can no longer influence the machining process of the workpiece.
- FIG. 6 schematically shows the sequence of a tool change in the machine tool 100 according to the invention.
- the illustration shows a) the machine tool 100 in the closed state, in which the first cover 30 and the second cover 40 are arranged essentially coplanar with one another.
- the illustration b) now shows that the first cover 30 was moved in such a way that the tool change area 80 (area between the first cover 30 and the machine table 10) was created in the immediate vicinity or adjacent to the work space 70 and the access area 42 to the tool change area has been released.
- Representation c) now shows how the work spindle 20 is positioned in the tool change area 80 and the tool changer 50 has been moved through the access area 42 into the tool change area 80, so that a tool picked up by the work spindle 20 can be exchanged / exchanged by the tool changer 50 .
- the tool changer 50 withdraws from the tool changing area 80 through the access area 42 and thereby enables the first cover 30 to be moved to close the access area 42 and the tool changing area 80.
- Representation e) again shows the machine tool 100 according to the invention in its closed state, in which the first cover 30 and the second cover 40 are again arranged essentially coplanar with one another.
- FIG. 7 schematically shows the movement of the work spindle 20 independently of the first cover 30, the first cover 30 also having wipers 33 for wiping cooling lubricants and material chips.
- FIG. 7 again shows the machine tool 100 according to the invention, which has essentially been reduced to the elements of the first cover 30 and the second cover 40 as well as the machine table 10 and the work spindle 20.
- the first cover 30 also has an opening 32 through which the carrier 22 extends, at the end section of which the work spindle 20 is arranged. This makes it possible for the carrier 22 to move the work spindle 20 in the y direction, regardless of the position or a method of the first cover 30.
- the first cover 30 in the region of the opening 32 has at least one scraper 33, which coolants and material chips, which occur during the machining of the workpiece and can deposit on the carrier 22, from Strips carrier 22.
- the work spindle 20 is positioned very close to the first cover 30 before a tool change or after a long machining of a workpiece, so that the largest possible number of material chips or the largest possible amount of cooling lubricant can be wiped off the carrier.
- the cooling lubricant stripped from the carrier 22 Material chips can thus be fed to the preparation and do not accumulate on the carrier 22 over a longer period of time.
- the illustration a) now shows the position of the carrier 22 with the work spindle 20 when it is essentially extended the most (maximum feed path of the work spindle 20 in the y direction).
- the illustration b) shows the work spindle 20 when it has been moved or positioned essentially up to the first cover 30, as a result of which the cooling lubricant and the material chips have been stripped from the carrier 22.
- FIG. 8 schematically shows the machine tool 100 according to the invention with a tool magazine 60 and linear axis 62 for the tool changer 50 attached to the side.
- the machine tool 100 according to the invention has been further reduced in this figure by the elements of the first cover 30 and the second cover 40.
- the tool magazine 60 is arranged laterally next to the carrier 22 on the movable stand in the x direction and additionally has the linear axis 62, through which the tool changer 50 travels through the access area 42 (not shown here) into the generated tool change area 80 can be to perform the tool change on the work spindle 20.
- a clear advantage of this construction is that the tool magazine 60 moves parallel to a movement of the work spindle 20 or of the carrier 22 in the x direction. This means that the tool change can essentially take place at any position of the work spindle 20 along the x-axis, without an additional infeed of the work spindle 20 in a specific “tool change position” along the x-axis.
- Such a construction also enables the slide for the delivery of the work spindle 20 to be constructed symmetrically in the y direction and to be structurally closed. Furthermore, it is possible to arrange drives for the slide centrally and, when using the work spindle 20 on the carrier 22 as a swivel head, allow a small distance between the B-axis around which the swivel head can rotate and the spindle nose receiving the tool, which has advantages in machine dynamics and rigidity brings.
- the tool magazine 60 can be designed as a chain magazine, as a wheel magazine or as a shelf magazine. Furthermore, an additional feed unit can also be provided, which removes the tool from the corresponding magazine and feeds it to the tool changer 50 before the latter changes the tool into the work spindle 20.
- the examples mentioned here are again to be understood as non-restrictive and can include further exemplary embodiments.
- FIG 9 schematically shows a machine tool known in the prior art, in which the tool change takes place in the area of the work space.
- the tool changer 50 usually or very frequently approaches the work spindle 20 in order to change the tool.
- the working space of the machine tool is cut off (work spindle 20 stands above the machine table 10 while the tool is being changed / exchanged by the tool changer 50).
- this entails the risks of the tool changer 50 colliding with the workpiece and / or e.g. the clamping device of the workpiece can come.
- FIG. 10 shows a flow chart of an exemplary embodiment of the method according to the invention for machining the workpiece.
- step S200 the workpiece is clamped on the machine table 10 of the machine tool 100 according to the invention.
- clamping devices such as clamping claws, mechanical or hydraulic workpiece clamps, a wide variety of jaw chucks etc. are used.
- the tool by means of which the workpiece is to be machined is now received in the work spindle 20.
- a wide variety of tools can be accommodated in the work spindle 20, in particular tools for machining the workpiece, which for example have a standardized receptacle such as a hollow shank taper or a steep taper.
- tools for machining the workpiece which for example have a standardized receptacle such as a hollow shank taper or a steep taper.
- other tool holders specific to the manufacturers of the tools can also be received by the work spindle 20.
- An appropriately equipped work spindle 20 is, however, a prerequisite for this.
- the machining in particular the machining of the workpiece, can now take place using the tool picked up by the work spindle 20 (step S400).
- the tool is guided through the work spindle 20 and through the infeed movements of the work spindle along the x, y and z axes along the workpiece or into the workpiece according to the NC program.
- additional infeed movements can also take place about a B axis (if the work spindle 20 is designed, for example, as a swivel head) or about a C axis (e.g. through a swiveling machine table 10, etc.).
- the first cover 30 is first moved in step S510, as a result of which the work space 70 of the machine tool 100 is expanded by the tool change area 80.
- the first cover 30 is moved in a direction which is directed out of the working space 70.
- the movement of the first cover 30 releases the access area 42, through which the tool changer 50 can be moved into the tool changing area 80.
- the tool changer 50 is moved accordingly through a linear axis 62 of the tool magazine 60 through the released access area 42 into the tool changing area 80.
- the work spindle 20 is then positioned in the tool change area 80, so that the tool changer 50 can exchange / replace the tool received by the work spindle 20 within the tool change area 80 (step S530).
